This is dated October 1996. It's another one of the Tab levels, from Michael Cimino, director of Heaven's Gate and The Deer Hunter. You fight 111 baddies in a slime cavern / techbase. It's easy - you get loads of health and rockets - and looks a bit nicer than the other Tab levels (the misaligned textures are generally deliberate). Much quicker gameplay than those "Reol Tough" maps from the same period. Don't bother saving the plasma ammo, you get plenty.
